Speaking about the pricing, Nexus 5 with 16 GB is reported to have 2,300 mAh for the battery as you could see in the technical manual and guess about the price? Ridiculously, it is only $299 off-contract.

Each model will have a different capacity battery powering the phone. With that in mind, we are told that the 16GB LG Nexus 5 will feature a 2300mAh battery and will be priced lock, stock and barrel for $299.

OEM battery is only about $10 or $15, so price alone won't tell you if it's genuine or not. I can't argue with that! When I searched on amazon.co.uk for OEM Nexus 5 battery, I found a few for only about £10 but the reivews made it clear that they were not really LG batteries.
